Description: The 2005 Hertfordshire Oil Storage Terminal fire was caused by a series of explosions early on the morning of 11 December 2005. The terminal, generally known as the Buncefield Depot, is an oil storage facility located near the M1 motorway on the edge of Hemel Hempstead in Hertfordshire, England. These were some of the largest explosions ever to occur in the country, and the incident has been described as the biggest of its kind in peacetime Europe. The tank fires were extinguished by the afternoon of 13 December 2005. However, one storage tank re-ignited in the evening, and the firefighters left it to burn, rather than attempting to re-extinguish it.
